Document delivery includes journal articles or conference papers etc. that have been photocopied from the print, to supplement high use collections and are made available for any researcher upon request for the current academic year. If a user request important research articles which are currently not available in any local library in Sri Lanka, the articles are requested by library to get them from the British Library Document Delivery Service (BLDDS). The payment required for these documents is borne by the library as Sida/SAREC supports the library to meet the cost.
